The aio CLI helps you to manage the .wskprops file as you use different namespaces.
You need npm installed in order to install it. Before you start, make sure you have the latest version of Node and npm installed.
npm install -g @adobe/aio-cli
After this, you can run help to see all the commands and verify that you are all set:
aio -h
If you want to update to the latest versions of any updated plugins, please reinstall the cli:
npm install -g @adobe/aio-cli
For more information about the aio CLI check the package home page.
